CROSS-ROLL TROU'GI-I.

Specification of Letters Patent.

Application filed March 1, 1910.

Patented May 24:, 1910. Serial No. 546,721.

To all whom it may concern:

Be it known that I, HARLEY D. PENNING- TON, of Pittsburg, Alleghenycounty, Pennsylvania, have invented a new and useful Cross-Roll Trough,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification, in Which Figure 1 is a plan view of a cross roll troughembodying my invention; Fig. 2 is a side View of the same; Fig. 3 is anenlarged side elevation of a portion of the apparatus, looking at itfrom the opposite side from Fig. 2; and Fig. 4 is a cross section on theirregular line IVIV ofFig. 3.

My invention relates to cross roll troughs, and is designed to provide atrough having means of simple, novel and eflicient character fordischarging the pipes or tubes from the trough.

The nature of my invention will be bes understood by reference to theaccompanying drawings, in which I have shown the preferred embodimentthereof, and which will now be described, it being premised,

however, that various changes may be made in the details ofconstruction, arrangement, and combination of the various parts by thoseskilled in the art, without departing from the spirit and scope of myinvention, as defined in the appended claims.

The numeral 2 designates the stationary supports of the apparatus, uponwhich are mounted the longitudinally extending parallel track rails 3.Mounted upon these track rails is an elongated carriage 4E, having theadjusting supports 5, which carry the trough. This trough is composed ofthe relatively fixed inclined sections 6, forming one side of thetrough, and the pivoted section 7, forming the other side of the trough,in which the pipes are received from the cross roll machine. The member7 of the trough is pivoted at 8, and is normally supported in theposition shown in full lines in Fig. 4:, by means of the verticallymovable .members 9, which are preferably provided with antifrictionrollers 10, at their upper ends, which form the direct supports for thepivoted trough section. In the apparatus illustrated, two of thesesupporting members 9 are shown, one near each end of the trough, but anydesired number may be used according to the length of the trough.

The vertically movable supporting members 9 are each formed with alongitudinally elongated slot 11. The upper wall of this slot has astraight portion 11 and an upwardly inclined portion 11 The framemembers 12 of the carriage at each side of the vertically movablesupporting members 9 and between which said members move, are formedwith longitudinal slots 13. Extending through the slots 11 and 13 is ashaft 14:, upon which are mounted three rollers 15, 16 and 17. Therollers 15 and 17 are arranged to travel on the lower edges of the slots13, while the roller 16 engages the upper wall of the slot 11 and formsthe support for the members 9. Each shaft 141 is carried at the upperend by an oblique arm 18, pivoted at its lower end 19 to one of thesupports 2 of the apparatus.

The carriage is arranged to be reciprocated on the track rails 3, bymeans of a hydraulic cylinder 20, or other suitable motive device,capable of giving the carriage a longitudinal reciprocating movementsomewhat less than the length of the slots 11.

The operation is as follows: The supporting rollers 16 are normally inthe positions shown in Figs. 2 and 3, being in engagement with thestraight portions 11 of the upper walls of the slots 11. In thisposition, said rollers hold the vertically movable members 9 in theposition shown in Fig. 4:, to keep the pivoted trough member 7 intrough-forming position. When, however, it is desired to discharge thepipes from the trough on to a receiver, such as the table 21, thecylinder 20 is actuated to move the carriage longitudinally to the right(looking at Figs. 1 and 2), and the rollers 16 will ride up the inclinedportions 11 of the slots 11, thus permitting the supporting members 9 todrop to this extent and permitting the pivoted trough 7 to assume thedischarging position shown in dotted lines in Fig. 4. The

pipes or tubes are thus permitted to roll out on to the receiving table21. The reverse movement of the carriage on the tracks will return therollers 16 into engagement with the straight portions 11 of the slotwalls,

and will raise the supporting members 9, and thereby the trough section7 to its normal receiving position.

The apparatus described forms a very simple and efficient one for thepurpose, and is capable of ready manipulation.

I claim:

1. A cross roll trough, comprising a longitudinally movable carriage, atrough carried thereby, said trough having a pivoted memher, and avertically movable support for the pivoted member, together with meanswhereby the longitudinal reciprocating movement of the carriage willraise and lower the support, substantially as described.

2. A cross roll trough, comprising a longitudinally movable carriage, atrough carried thereby, said trough having a pivoted member, a pair ofvertically movable members supporting the movable section of the troughnear opposite ends thereof, and connections operated by the longitudinalreciprocating movement of the carriage for raising and lowering saidmembers, substantially as described.

3. A cross roll trough, comprising a longitudinally movable carriage,means for reciprocating the carriage, a trough supported by the carriageand having a pivoted side member, a vertically movable member form ing asupport for the pivoted side member, and a relatively stationary arm orlever engaging the supporting member to raise and lower the same whenthe carriage is reciprocated, substantially as described.

4. A cross roll trough, comprising a longitudinally movable carriage,means for reciprocating the carriage, a trough carried by the carriageand having a pivoted side member, a plurality of vertically movablemembers forming a support for the pivoted side member, said supportingmembers having cam slots therein, and arms or levers pivotally connectedto the stationary bed of the apparatus and having rollers engaging saidcam slots, substantially as described.

5. A cross roll trough, comprising a longitudinally movable carriage,means for reciprocating the carriage, a trough carried by the carriageand having a pivoted side member, a plurality of vertically movablemembers forming a support for the pivoted side member, said supportingmembers having cam slots therein, and arms or lever pivotally connectedto the stationary bed of the apparatus and having rollers engaging saidcam slots, said arms or levers also carrying other rollers and thecarriage having bearings for said rollers, substantially as described.

In testimony whereof, I have hereunto set my hand.
